The worst service ever

Today I had the worst experience when it comes to customer service. Me and my friends went to Preston’s to go get wine and a cold drink . On the way home we noticed that the Stoney cold drink we had was expired. We than went back to Preston’s to return it and let them know they have expired goods. When we got at Preston’s I asked for the manager and as if she was waiting for me, she starts being defensive . All I asked was why is Preston’s selling old goods, she answered stating that Coca Cola is the reasons why there is old goods in their store. I answered telling her that I don’t buy from Coca Cola I buy at Preston’s and Preston’s is the one selling me old goods. She said it was coca colas fault and not theirs . She continues being rude never apologizing for the current situation. I told her about her repeated disregard of us when we at the store, and her obvious preference for white customers. All she did is tell me to leave the store and never come back because of returning old goods, she never acknowlege the fact that they sold us old goods. My friend is vomiting , and feeling sick . Is this how Preston’s treats their customers ? The amount of times we shop at the 9th Avenue store never mind the money we spend and to be treated like that . Is it actually Coca Cola that doesn’t care about us? because according to Preston’s management they selling old goods because of them. Must I apologies for shopping while black, because it is evendant that shopping while black at Preston’s is a problem .
